Thank you everyone
Personally, I don’t find the Greek Mythology connections to be especially noticeable. I see where you’re coming from, but I don’t see it as much of a problem! The only issue for me is that the combination feels a bit rhymey, [name_f]Aurora[/name_f] [name_f]Callista[/name_f] flows better in my opinion. These two names sound lovely together!
Agree with pp, it’s more the order that’s not quite right, with the A at end of [name_f]Callista[/name_f] ramming into A of [name_f]Aurora[/name_f] (and their similar rhythm). But I prefer [name_f]Callista[/name_f] as a first so if it were me, I’d be finding a new middle.
Should add: last name is key here, could make my “criticisms” insignificant once flows to a last name that makes it all work.
I don’t think it’s too much, especially as it’s a mix of mythologies, and I am somewhat swayed by the combined ‘Beautiful [name_f]Dawn[/name_f]’ meaning. It’s a nice sounding combo in my opinion, if a little verbally complex.
I don’t think both being tied to mythology is a big deal at all. Though saying it feels awkward to me… the a at the end of [name_f]Calista[/name_f] and beginning of [name_f]Aurora[/name_f] is a bit of a tongue twister.
Thanks to everyone who responded. I probably should’ve been more specific, but I think what I find weird is that each name references a person in greek mythology: [name_f]Callista[/name_f] was a nymph and [name_f]Aurora[/name_f] was a goddess. Does no one find that weird with the use of those two names together?
I don’t think it’s strange at all! These names are both beautiful and flow well together. If anything, the subtle tie via Greek mythology is an extra boost.
I think you overthink it. 
[name_f]Callista[/name_f] [name_f]Aurora[/name_f] is beautiful, though a bit of a tounge twister. I love both names a lot, but unsure about them together due to the flow. The greek myth connection is no biggie though.
Not important imo.
Personally I don’t think it’s important. And if it makes any difference the Greek nymph was called [name_f]Callisto[/name_f] rather than [name_f]Callista[/name_f].
I wouldn’t have noticed the connection without you pointing it out.
Honestly, yes, even though the nymph was [name_f]Callisto[/name_f], it’s so close, and I would notice, and no, I wouldn’t use them together because it’s not my cup of tea. However, I do think they are really beautiful names, and if you really love the combo you can comfort yourself with the fact that [name_f]Callista[/name_f] is just derived from the myth of [name_f]Callisto[/name_f], so it would be more like using [name_u]Echo[/name_u] [name_f]Demetria[/name_f] or [name_f]Juno[/name_f] [name_f]Diane[/name_f], which is more reasonable than using something like [name_m]Odin[/name_m] [name_m]Thor[/name_m] or [name_f]Hera[/name_f] [name_f]Persephone[/name_f].
I don’t find using the names together to be an issue…most people aren’t ever going to be aware of the namesakes in Greek mythology. I might use the [name_m]French[/name_m] form of [name_f]Aurora[/name_f], [name_f]Aurore[/name_f], instead to have different endings on the names, but don’t find [name_f]Callista[/name_f] [name_f]Aurora[/name_f] difficult to say.
I don’t think the fact they are both from Greek mythology is an issue, but the names are pretty rhymey. They’re both lovely though and I can see the appeal in the combo.
